Aubrieta plant named ‘Audelpur’

ABSTRACT

A new  Aubrieta  plant, characterized particularly as to novelty by the purple flowers, the early flowering and the strong dentation of the leaves.

Latin name of the genus and species of the plant claimed: Aubrieta hybrida.

Varietal denomination: ‘Audelpur’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new distinct cultivar of Aubrieta, botanically known as Aubrieta hybrida.

The new Aubrieta is a product of a planned breeding program conducted in Enkhuizen, Netherlands. The new Aubrieta cultivar has a compact growth habit and an early flowering in several colors.

The present cultivar originates from a cross-pollination made in 1998, of a proprietary Aubrieta selection identified as ‘A002,’ not patented, as the female, or seed parent, with a proprietary Aubrieta selection identified as ‘A009,’ not patented, as the male, or pollen parent. A seedling from this cross was selected in 1999.

The present cultivar has been repeatedly asexually reproduced by cuttings in Enkhuizen, Netherlands, in Angers, France, in Gilroy, USA since 1999. The distinctive characteristics of this new Aubrieta are stable and reproduced true to type in successive generations of asexual reproduction. It takes 25 to 29 weeks to produce a finished plant, depending on the temperature.

This new Aubrieta plant is a perennial in all climatic zones in the US.

DESCRIPTION OF THE DRAWING

This new Aubrieta plant is illustrated by the accompanying photographic drawing of a 28 week old plant which shows blooms, buds and foliage of the plant in full color, the color showing being as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of this new Aubrieta. The data which defines these characteristics were collected from asexual reproductions carried out in Enkhuizen, Netherlands. The plant history was taken on 35 week old plants, blossomed under natural light in the field.

Color readings were taken in the office under ambient light. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London.

Plants of the new Aubrieta differ primarily from the plants of the female parent selection in the following characteristics:

Plants of the new variety have purple flowers and a compact growth habit, whereas plants of the female parent selection have red flowers and a very loose growth habit.

Plants of the new Aubrieta differ primarily from the plants of the male parent selection in the following characteristics:

Plants of the new variety have purple flowers and an early flowering, whereas plants of the male parent selection have mid blue flowers and a late flowering.
